A firearm reload system that enables the reloading of a firearm with a single user action. The firearm reload system can include an automatic ammunition chambering system and an empty magazine auto-eject system. The automatic ammunition chambering system includes an actuator on a magazine that actuates a pivoting slide lock when the magazine is introduced into the firearm frame, causing the pivoting slide lock to disengage from the firearm's slide release, thereby freeing the slide and chambering a cartridge. The magazine auto-eject system includes a magazine actuator linking the slide release and the magazine release such that when the slide release is brought into a locked position, the magazine actuator actuates the magazine release such that the magazine is released from the firearm.
